Reindexing one site with Erase

Hi, Is there an easy way to reindex just one site at a time with erase?

I found the post that explains how to reindex ALL sites with Erase, but I was wondering if there was a way to reindex just one site with erase instead. We have 20 different sites, so I'd rather not do them all at once. (here's the post I'm referring to: [www.sphider.eu])

i'd like to reindex the site to "ignore parts of the page" and have been told that I must erase the index first (http://www.sphider.eu/docs.php#ignparts).

thanks in advance,
sarah

I believe that if you reindex a site with a good must not include string everything that does include that string will be removed from the database.

For instance, if your site consists of .html pages you can place .html in the must not include box and reindex.
After that all pages with a .html extension will have been removed from the index.
Now you can do a reindex without a must include/must not include string, all removed pages will be reindexed.
